I have a telescoping cover, so I was thinking that I'd use some 1×2s to make a short box, and cut out a notch or a hole in one side, and place this on top of the inner cover to make a top entrance. Will they end up filling this with comb, or is it a viable plan? If it's viable, could I then turn it into a middle entrance by adding honey supers on top (when that time comes)?
